Provide technical operations and environment support for a large-scale Auto Finance Platform serving multiple international automotive finance clients. Focus on ensuring data integrity and batch process reliability across Test and UAT environments that simulate production systems. Key Responsibilities: • Monitor and validate mainframe batch jobs (JCL, datasets, file transfers) in test and UAT cycles. • Coordinate and execute environment preparations for UAT releases and regression testing. • Support multiple clients and regional units by ensuring data flows and system interfaces are accurate. • Troubleshoot job failures and data issues, perform root-cause analysis, and escalate to development teams. • Maintain technical documentation for batch processes and environment configurations. • Collaborate with cross-functional teams to enhance operational efficiency and test environment stability. Key Achievements: • Supported complex test and UAT operations across 4 global clients and multiple regional units. • Improved environment readiness and reduced cycle execution delays through process optimization. • Strengthened communication and issue-tracking flows between operations and development teams. Technical Environment: Mainframe (z/OS), ISPF, JCL, Control-M, File Datasets, FTP/SFTP, UAT & Test Environments, Batch Scheduling, SQL, Incident & Change Management.
Designed and developed end-to-end banking transaction screens from scratch, managing both functional and technical requirements across multiple clients and transaction types. Programmed in ADL, performed unit testing, and debugged programs using log analysis, ensuring accurate and reliable outputs. Managed frontend (Java drag-and-drop interfaces) and backend (Oracle, SuperPuTTY), handling complex financial workflows. Collaborated closely with Business Analysts (BA) and QA teams to interpret Jira requests, clarify functional requirements, validate deliverables, and implement corrections efficiently. Utilized tools including WinSCP, Notepad++, Citrix, PowerPoint, Excel, and Word for file operations, data validation, reporting, presentations, and accessing virtual environments. Worked across multiple virtual machines (VMs) — client-specific, testing, and consulting — ensuring isolated, consistent, and high-quality execution. Followed Scrum and Agile methodologies, actively participating in sprint planning, daily stand-ups, and sprint reviews to deliver incremental improvements. Presented updates and workflows to stakeholders via Teams, ensuring transparency and alignment on project progress
Mainframe application development and migration using COBOL, DB2, and JCL, with full technical ownership of complex backend projects. Main Responsibilities & Achievements: Designed, developed, and maintained COBOL programs, DB2 datasets, JCL scripts, PSB, PDS, and TSI components. Easytrieve to COBOL Migration (Full Project Ownership): Managed the entire life cycle independently, from functional analysis to production deployment. Rebuilt all programs in COBOL, ensuring outputs identical to the original Easytrieve reports — including every decimal detail in monthly and yearly banking reports. Authored and executed all JCL scripts for testing and production. Performed multiple debugging and validation iterations to guarantee 100% output accuracy. Documented the process in a technical pocket guide for internal use. Billing Web Interface – Backend Development: Fully handled the backend implementation for migrating IBM 3270 billing screens to modern web-based interfaces. Designed and created all DB2 database structures: tables, tablespaces, sequences, and datasets. Built and configured TSI and PSB components. Used SPUFI for executing and validating DB2 object creation scripts. Collaborated with a C# developer responsible for the frontend, performing joint unit and integration testing across Test, UAT, and Production environments. Conducted quality assurance using QCHP (Quality Center) and provided technical maintenance support for COBOL applications.
